So I am wondering if I should try my luck again after a win, or should I still take a break?
The gambler who wins consecutively in every session surely thinks the same as you. Luck is not something we can have all the time, and when we have it, we feel that it's time to win more. It is not wrong for you to take a break. The confidence to win can sometimes turn a victory into a defeat. It would be better to enjoy the victory first and return to betting when your mind is calm.
